VALVE MECHANISM on INTEnivAL-ooMBUsrIoN ENGINES.

' Applicationfil ed September 27, 1920. Serial N'o. 412,942.

-Be it known that I,- AUeUs'r lViLLEN- snoom acitizenof the United States residingat Richmond 'Hill, in-the county of Queens and. State of New York, have invented new and useful Improvements in Valve .Mechanism for Internal Combustion.

Engines, of which the following is a specification.

This invention: relates to improvements in valve mechanism for internal combustion engines, and one of the principal objects is to provide a simple and efficient disk valve.

Another objectis to provide improved baffling and disintegrating means for the fuel. I V

Another object is to provide an improved oiling system. 7

Another object is to provide a spring pressed valve seat.

With these and otherobjects in View the invention consists in certain novel construction and combination and arrangement of parts, the essential features of which are set forth in the following description, and particularly pointed out in the appended claims, and one embodimentof which is shown in the accompanying drawing comprising two sheets, in which 1 Figure 1 is a vertical sectional view of a cylinder of an internal combustion engine provided with my improved valve mechanism.

Figure 2 is a View taken substantially in line 22, of Figure 1. I

Figure 3 is a detail view of the valve per se. a

Referring to the drawing in detail, 1 represents the cylinder of an internal combus tion engine'provided with the usual piston 2 and intake port 3;

Mounted in the intake port 3 is a member 4: mounted for movement longitudinally of the cylinder and providedwith expansion rings 5 for sealing contact with the sides of the intake 3. The member 4 is surrounded by a spring 6 hearing at its lower end against the cylinder and at its upper end against a shoulder 7 of member land tending constantly to force said member 4 outwardly. Member 4- is provided at its outer end with a curved face 8 and has a'plurality of oil ducts 9 leading to said face 8.

The cylinder head is shown at 1O-1O and is in two parts provided with leads 11 and 12," the first of which connecting with the intake manifold :13 and the lead-12 connecting with the exhaust manifold. It will be seenthat the intake lead 11 has several sharp turns which baflle the air and gas and cause amore complete mixture. Rotatablymounted in bearings in the cylinder head and in a bracket 14:, is a valve shaft 15 which may comprise several parts joined together by universal'joints as at 16. This shaft may be driven by any suitable positive means, as, for instance, by a sprocket wheel 17 and chain 18.

A valve disk 19 is secured on shaft 15 and is provided in its edge'with intake and exare adapted to register with the respective leads 11 and 12 and connect the same with the lead 22through the member 1. The

cross-sectional area of the exhaust passage is in all places at least'as great as'the crosssectional area of the lead 22 so as to permit a compression. In the above described device the face 8 is pressed by spring 6 into such intimate contact with the edge of the disk 19 that a tight seal is constantly maintained. And, further, the valve and the face 8 grind against each other so as to produce a perfeet fit. v

The oiling system includes a lead pipe 24 from which the oil is forced under pressure into a well 25. As the oil rises in well 25 it is forced through ducts 9 against the face of the'disk 19. The disk is provided with a groove 26 which is adapted to receive a quantity of oil from ducts 9 and distribute it around the surface of the bearing of disk 19 in numberlO. When the oil rises in well 25 toa point above an outlet pipe 27, it flows into said outlet pipe and is conducted away thereby.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the de- 70 haust ports 20 and 21, respectively, which tails may be Varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the wholeof my invention limited only by the appended claims.

What I claim as new and desire to secure by Letters Patent is 1. In combination with the rotatable valve disk of an internal combustion engine, of a bearing therefor, a member having a seat for said disk, means for normally holding said member seated against the periphery of said valve disk, a well disposed below said seat, an inlet pipe leading to said well for supplying oil thereto, openings communicating with said well and said seat, a groove formed in the periphery of said valve disk for register with the openings in said member whereby to distribute oil about said bearing upon rotation of the valve disk, and an outlet pipe leading from said well for carrying ofl' oil from said well when the same reaches a predetermined level.

2. In combination with the rotatable valve disk of an internal combustion engine, 01 a bearing therefor, a member having a seat for said disk, means for normally holding said member seated against the periphery of said valve disk, a well disposed below said seat, openings communicating with said well and said seat, a groove formed in the periphery of said valve disk for register with the openings in said member whereby to distribute oil about said bearing upon rotation of the valve disk.

In testimony whereof I have ai'lixed my signature.
